NITED STATES PATENT OFFICE.

IMPROVEMENT IN WASTE-SAVING ATTACHMENT T0 CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 47,274, dated April I8, 1865.

To all zhom it may concern:

Be it known that l, ANTHONY A. BENNETT, ot' the town of Norwalk, county ot' Fairtield, and State of Connecticut, have invented a new and useful Improvement in the ConstrucA tion of Carding-Engines and I do hereby dcclare that the following is a full, clear, and exact description thereof, reference bein g had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement and application of a curved frame-work or shell, with a plain metallic or other face, to be placed under the main cylinder, and a revolving receptacle guard-roller, to retain the short waste liber escaping from the revolving ofthe main cylinder.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 1 is a side view of a portion ol' a cai-ding engine and t'rame with part of the l'ramc removed to show my improvements. Fig. 2 is a plan or surface view showing the metal lace and the receptacle guard-roller.

The mechanical arrangements and the various rollers and attachments belonging to a carding engine will all remain without alteration. My improvements will notinterfere with them or their operations. I make a curved frame, A, to be placed under the main cylinder B, of nearly the same radius as the cylinder and of the same length horizontally, eX- tending f rom the receptacle guard-blade roller C to the tumbler-roller D. On the upper side of this frame or the'inncrV periphery of the same, I bend and attach sheet metal A a, or some other substance, to form aplaiu surface, extending the whole distance of the curved frame A, and following under the tumblerroller D, and which is then fastened to the cross-bar Il. The curved surface is placed in close proximity to the peiiphery of the cylinder and tumbler, and is attached to the main frame L by the supporting-brackets M.

I make the receptacle guarderoller C of the same length as the main cylinder, audozi the periphery of the saine I attach a series of thin metal blades ed gewise, running in a spiral direction, as shown in the drawings. This roller C is placed so that the edges ot' the blades will revolve close to the back edge ot' the curved-metal-covered frame A beneath this roller. I attach to the frame L a bar, G, and on the side of this bar I fasten vertically a strip of leather, or its equivalent, as a brush, rising a certain distance above the upper edge of the bar, so that when thc roller C revolves the edges of the blades will touch the same, and the heavy dirt or dust falling on and between the blades will be brushed oft and fall on the floor.

The object of the blade-roller C is to prevent the current ot' air caused by the quick revolution of the main cylinder from drawing the short fine ber away from the doft'er F, in consequence of the current of air being broken by the close proximity of the blades of the roller C to the edge of the frame of the curved shell A, and at the same time the heavy dirt or dust will fall on and be retained by and between the blades ofthe receptaelcroller C, and be brushed ott' and cleared by the leather K. The receptacle guard-roller C is revolved at any required speed by the belt and pulleys I, connected with the doft'er F or by gearwheels. By these arrangements the short liber is retained with the long fiber, and passes directly on to the doffer F without waste, effectually cleared from'dust or other impurities. i

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the curved shell wastesaver A, having a plain i'ace, and the receptacle guard-roller C, or their equivalents, in the manner and for the purpose substan` tially as herein described.

2. The clearing-brush Gr, or its equivalent, operating iu combination with the waste-saver A and the guard-roller C, for the purpose de scribed.

A. A. BENNETT.
